ARTIFICIAL STONE.

Mt -"l/ SPECIFICATION forming part of Letters Patent No. 284,299, dated September 4, 1883,

Application filed June 11, 1883. (No specimens.) I

.To aZZ whom it ma'y concern:

Be it known that 1, PETER F. HATERTY, a citizen of the United States, residing at Shenandoah, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Artificial Stone; and I dodeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it IO appertains to make and use the same.

My invention consists in the composition of the following ingredients and solutions, mixed and combined in the manner hereinafter set forth.

I 5 I take of Portland cement. three parts; marble-dust. two parts";"c can sharp SHIN. one part; astcr-otwaris. one part. XII or these ingrct rents are to e thoroughly mixed together in a dry state. I then form a solution by dissolving, in four gallons of water, sal-an1- inoniac. four ounces; hartshorn, fourm? \VtlSIllIlfI-Sfltlil, eight ounc s; an to this I add one quar ot venziuo. I 1 ake another solution of two pounds ot'good 5 no in four gallons of water.

0 make my artifici. stone I take one-half gallon of the first solu ion, add six gallons of water to it, and then dd the glue solution in a warm state, thorou hly stirring and mixing all together. This fi al mixture should stand not less than an hour and then should be mixed with the cement, sa 1d, &c., so that the whole forms a stiff mass, which is to be molded or formed as may be desired. This composition will harden very readily, and will resist the 5 action of the weather. It maybe made of any density desired, and maybe colored to imitate any colored natural stone.

In the preparation of artificial-stone for Va rious uses it is necessaryto produce soft orhard 0 stone, as occasion requires, and this is easily accomplished by varying the proportions of cement, sand, &c., or by omitting the plaster of-paris or m'arbledust, the mixing solutions remaining as herein stated.

I am aware that some of the ingredients I use have heretofore been used for the manufacture of artificial stone; but I am not aware that all the ingredients, as I combine and use them in my composition, have ever before been used for that purpose.

hat I claim, and desire to secure by Letters Patent, is-

The composition for the manufacture of artificial stone herein set forth, consisting of a 5 5 mixture of sand, cement, marble-dust, plasterof-paris, sal-ammoniac, hartshorn, washingsoda, benzine, glue, and water.

In testimony whereof I affix my signature in presence of two witnesses.

PETER F. HAVERTY.
